关键词： 文化自信   跨文化交际   文化意识   英语教学  

摘要： 《普通高中英语课程标准(2017年版)》中,文化意识被列为英语学科核心素养之一。在英语教学过程中,注重培养学生的文化意识,既有助于消除"中国文化失语"的现象,也便于培养跨文化交际人才,让"中国文化走出去"。本课题主要针对目前英语教学中传统文化输入欠缺的问题,提出培养学生文化意识的实践方法,进一步提高学生的文化自信。

关键词： 礼貌待人   礼貌用语   文明交往   早上好   幼儿园   话语形式   春节期间   全托  

摘要： “问好”,表示人们在交际中对对方的“尊重和欢迎”,是礼貌待人的第一步. “问好”的基本话语形式是“您好”,这在文明交往中的使用频率最高,也是儿童学习礼貌时最先学得的礼貌用语.但在不同的时间和场合,“问好”有各种变体.按汉族人的习俗,早晨第一次相遇,说“您早”“早上好”“早”的多于“您好”;元旦、春节期间见面则多是“新年好”“春节好”“恭喜恭喜”等. 日本人回家时说:“我回来了.”这种“通报”也是一种问好.而汉族小孩儿回家时喊一声“爸爸!”“妈妈!”,则是一种“中国式”的问好.事实上我们较少听见小朋友放学回家说“爸爸好!”“妈妈好!”,除非是上全托幼儿园的孩子,或是已有一段时间没与父母见面才会这样说.

摘要： 近年来,世界掀起了一股“汉语热”的浪潮,越来越多的外国友人对中国语言和文化产生了浓厚的兴趣,促进了对外汉语的蓬勃发展。在这样的时代背景下,跨文化交际逐渐兴起,同时一些现代化对外汉语教材应运而生。以多媒体教材《环球汉语2》为例,从言语交际和非语言交际两个层面分析跨文化交际在教材中的应用,并提出对外汉语文化教学的策略。

关键词： cognitive strategies   digital learning environments   self-regulated learning   skill training   STEM education  

摘要： Students who drop out of their science, technology, engineering, and math (STEM) majors commonly report that they lack skills critical to STEM learning and career pursuits. Many training programs exist to develop students' learning skills and they typically achieve small to medium effects on behaviors and performance. However, these programs require large investments of students' and instructors' time and effort, which limits their applicability to large lecture course formats commonly employed in early undergraduate STEM coursework. This study examined whether brief, digital training modules designed to help students apply learning strategies and self-regulated learning principles effectively in their STEM courses can impact students' behaviors and performance in a large biology lecture course. Results indicate that a 2-hr Science of Learning to Learn training had significant effects on students' use of resources for planning, monitoring, and strategy use, and improved scores on quizzes and exams. These findings indicate that a brief, self-guided, online training can increase desirable learning behaviors and improve STEM performance with minimal cost to learners or instructors. Implications for future design of interventions and their provision to students in need of support are discussed.

关键词： medication-related osteonecrosis of the jaw   local flap   maxilla  

摘要： Stage 3 medication-related osteonecrosis of the jaw (MRONJ) requires surgical treatment for resolution of the pathology. In the maxilla, removal of the necrotic bone and infected soft tissue leads to large defects with oroantral communications. It is essential to cover the exposed bone and close the communications by using wellvascularized soft tissue for good long-term results without a relapse of the osteonecrosis. Here, we evaluated the technical usefulness of the inferior-based nasolabial flap (IBNF) for covering the exposed bone and closing the oroantral communications in maxillary stage 3 MRONJ after complete decortication and sinusotomy. No problems were noted in the treated areas in four patients at 12 months postoperatively. Despite the limited number of cases, the IBNF may be a reliable and simple method for the reconstruction of relatively large defects and the closure of oroantral communications in maxillary stage 3 MRONJ without complications.

关键词： glycogenolysis   cattle   glycogen   liver  

摘要： Glycogen, a complex polysaccharide, is the form of storage of glucose in mammals that can be released rapidly when needed. Recent studies have mainly reported hepatic glycogen concentration for early-lactating cows, when the energy demand is higher than the energy supply from dry matter intake, driving the cow to use the energy stored as hepatic glycogen. Generally, liver samples are obtained through percutaneous needle biopsies in the right lobe of the liver. Our objective was to analyze the variation of glycogen concentration in the livers of Holstein and Jersey cows among different liver locations representing all lobes, to evaluate whether samples obtained by liver biopsies are representative of the whole organ. Liver from 10 culled lactating cows (5 Holstein and 5 Jersey cows) from 30 to 113 mo of age at slaughter were obtained. Each liver was sampled no more than 3 h after death on the following sites: 3 sites in the right lobe (1 to 3), 2 in the diaphragmatic surface of the left lobe (4 and 5), 3 in the visceral surface of the left lobe (6 to 8), 1 in the quadrate lobe (9), and 1 in the caudate lobe (10). Samples were snap frozen in liquid N2 and were then analyzed for glucose concentration after conversion of glycogen to glucose using amyloglucosidase (EC 3.***.1.3). Glycogen results are reported as grams of glucose per 100 g of wet weight of liver (i.e., percent of wet weight of liver). Liver weights averaged 5.1 [standard deviation (SD) 1.2, minimum 3.3, maximum 6.2] kg for Holstein and 6.0 (SD 1.8, minimum 4.7, maximum 8.9) kg for Jersey cows. Holstein cows [1.31, standard error of the mean (SEM) 0.05% of wet weight] had greater liver glycogen concentration than did Jersey cows (0.75, SEM 0.05% of wet weight). No significant difference was noted among the 10 liver locations regarding glycogen concentration and averaged, for both breeds, 1.03% of wet weight (SEM 0.10). These results suggest that, in dairy cows, percutaneous needle liver biopsy in the right l

摘要： This work aims to study the dosimetrc parameters of the new Co-60-source model CoO.A86 used in high dose rate brachytherapy and manufactured by BEBIG (Eckert & Ziegler BEBIG GmbH, Germany). The radial dose function, 2D along&away dose rates and the dose rate constant were investigated in a water phantom. Accordingly, we use the recommendations from the AAPM and ESTRO on dose calculation for high-energy (average energy higher than 50 keV) photon-emitting brachytherapy sources cited in the HEBD working group report. Furthermore, we compared the obtained results with the quoted values in the previous studies. The value of air-kerma strength calculated in this work was 3.030 +/- 0.002 IL13q(-1). Moreover, the radial dose function and 2D along&away dose rates are evaluated in different tissues and compared with the results obtained in the water and we found a notable difference. To reach the goal we have used MCNPX code for simulation.
